Abstract

Системы воздушных фильтров, описанные в настоящем документе, включают один или несколько коллекторов импульсов и генераторов импульсов, центрированных вдоль осей импульсов. Генераторы импульсов и фильтрующие элементы могут быть расположены вдоль длины пути импульса, измеренной от выходного отверстия импульса до отверстия фильтрующего элемента. Коллекторы импульсов и фильтрующие элементы могут иметь отверстия, между которыми существует взаимосвязь в пределах параметров, описанных в настоящем документе. Коллекторы импульсов могут иметь взаимосвязь между их гидравлическим диаметром и их длиной в пределах параметров, описанных в настоящем документе. Коллекторы импульсов могут содержать фильтрующую секцию и импульсную секцию, которые сведены в месте стыка вдоль длины коллектора импульсов. Импульсные секции могут иметь гидравлический диаметр, который увеличивается при движении от места стыка к отверстию трубной решетки импульсной секции. Фильтрующие секции могут иметь гидравлический диаметр, который остается неизменным при движении от места стыка к фильтрующему концевому отверстию фильтрующей секции. Фильтрующие элементы/патроны, применяемые в системах воздушных фильтров, могут иметь фильтрующую среду, профилированную или формованную с образованием яйцевидных поперечных сечений.
